400-587: A big impact on information security in organizations. Cultural concepts can help different segments of the organization work effectively or work against effectiveness toward information security within an organization. Information security culture is the "...totality of patterns of behavior in an organization that contributes to the protection of information of all kinds." Andersson and Reimers (2014) found that employees often do not see themselves as part of their organization's information security effort and often take actions that impede organizational changes. Indeed,

The severity of attacks can range from attacks simply sending an unsolicited email to a ransomware attack on large amounts of data. Privilege escalation usually starts with social engineering techniques, often phishing . Privilege escalation can be separated into two strategies, horizontal and vertical privilege escalation: Any computational system affects its environment in some form. This effect it has on its environment can range from electromagnetic radiation, to residual effect on RAM cells which as

Such attacks can originate from the zombie computers of a botnet or from a range of other possible techniques, including distributed reflective denial-of-service (DRDoS), where innocent systems are fooled into sending traffic to the victim. With such attacks, the amplification factor makes the attack easier for the attacker because they have to use little bandwidth themselves. To understand why attackers may carry out these attacks, see

These figures were much higher for "medium businesses (59%), large businesses (69%), and high-income charities with £500,000 or more in annual income (56%)." Yet, although medium or large businesses are more often
4500-436: The "practice of designing computer systems to achieve security goals." These goals have overlap with the principles of "security by design" explored above, including to "make initial compromise of the system difficult," and to "limit the impact of any compromise." In practice, the role of a security architect would be to ensure the structure of a system reinforces the security of the system, and that new changes are safe and meet
4600-407: The 'attacker motivation' section. A direct-access attack is when an unauthorized user (an attacker) gains physical access to a computer, most likely to directly copy data from it or steal information.

However, they are also multi-staged, meaning that “they can infiltrate networks and move laterally inside the network.” The attacks can be polymorphic, meaning that the cyberattacks used such as viruses, worms or trojans “constantly change (“morph”) making it nearly impossible to detect them using signature-based defences.” Phishing is the attempt of acquiring sensitive information such as usernames, passwords, and credit card details directly from users by deceiving

7500-449: The life-threatening risk of spoofing in the healthcare industry. Tampering describes a malicious modification or alteration of data. It is an intentional but unauthorized act resulting in the modification of a system, components of systems, its intended behavior, or data. So-called Evil Maid attacks and security services planting of surveillance capability into routers are examples. HTML smuggling allows an attacker to "smuggle"
7600-527: The main techniques of social engineering are phishing attacks.

7800-556: The most significant new challenges facing the contemporary world, due to both the complexity of information systems and the societies they support. Security is particularly crucial for systems that govern large-scale systems with far-reaching physical effects, such as power distribution , elections , and finance .

IT security
7900-473: The nature of backdoors, they are of greater concern to companies and databases as opposed to individuals. Backdoors may be added by an authorized party to allow some legitimate access or by an attacker for malicious reasons. Criminals often use malware to install backdoors, giving them remote administrative access to a system. Once they have access, cybercriminals can "modify files, steal personal information, install unwanted software, and even take control of
8000-560: The openness of the Internet. These strategies mostly include phishing , ransomware , water holing and scanning. To secure a computer system, it is important to understand the attacks that can be made against it, and these threats can typically be classified into one of the following categories: A backdoor in a computer system, a cryptosystem , or an algorithm is any secret method of bypassing normal authentication or security controls. These weaknesses may exist for many reasons, including original design or poor configuration. Due to
8100-428: The real website. Preying on a victim's trust, phishing can be classified as a form of social engineering . Attackers can use creative ways to gain access to real accounts.

A more strategic type of phishing
8200-476: The right foundation to systematically address business, IT and security concerns in an organization.

It also specifies when and where to apply security controls. The design process is generally reproducible." The key attributes of security architecture are: Practicing security architecture provides
8700-448: The software at all. The attacker can insert the software onto a compromised device, perhaps by direct insertion or perhaps by a virus or other malware, and then come back some time later to retrieve any data that is found or trigger the software to send the data at some determined time." Using a virtual private network (VPN), which encrypts data between two points, is one of the most common forms of protection against eavesdropping. Using
8800-677: The system to the attacker, and can corrupt or delete data permanently. Another type of malware is ransomware , which is when "malware installs itself onto a victim's machine, encrypts their files, and then turns around and demands a ransom (usually in Bitcoin ) to return that data to the user." Types of malware include some of the following: Man-in-the-middle attacks (MITM) involve a malicious attacker trying to intercept, surveil or modify communications between two parties by spoofing one or both party's identities and injecting themselves in-between. Types of MITM attacks include: Surfacing in 2017,
8900-428: The team's employees' 2015 W-2 tax forms.

The malware, named by Trellix as Graphite, employs Microsoft Graph to use OneDrive as
9100-427: The users. Phishing is typically carried out by email spoofing , instant messaging , text message , or on a phone call. They often direct users to enter details at a fake website whose look and feel are almost identical to the legitimate one. The fake website often asks for personal information, such as login details and passwords. This information can then be used to gain access to the individual's real account on
9200-616: The victims, since larger companies have generally improved their security over the last decade, small and midsize businesses (SMBs) have also become increasingly vulnerable as they often "do not have advanced tools to defend the business." SMBs are most likely to be affected by malware, ransomware, phishing, man-in-the-middle attacks , and Denial-of Service (DoS) Attacks. Normal internet users are most likely to be affected by untargeted cyberattacks. These are where attackers indiscriminately target as many devices, services, or users as possible. They do this using techniques that take advantage of
